28129 and 28130— Continued. 



28130. Ziziphus oxyphylla Edgew. 



"Qadhmani. This name refers to the fact that they can be chewed up, stones 

 and all. Some call them 'Makki,' as they are thought to have been introduced 

 here from the city of Mecca." 



Distribution. — Found occasionally on the eastern flanks of the Sulaiman 

 Range and in the outer Himalayas as far as the Ganges, in northwestern India. 



"The jujube tree grows in this dry country without any attention or irrigation. 

 The fruit is relished by the natives, but I do not think Americans will care for it. It 

 ha3 a taste vaguely resembling the red haw of Texas, if the memories of my childhood 

 do not play me false. The English call the fruit I have sent you c nubbuch apples. 1 

 The Arabic name of the fruit is 'Nabaq,' the tree is called 'Sidr.' " 



Note. — The Tournefortian genus Ziziphus was not recognized by Linnaeus in his 

 Species Plantarum but was united with Rhamnus, and the five species known to 

 Linnaeus were included as Rhamnus lotus, R. jujuba, R. oenopolia, R. zizyphus, and 

 R. spina-christi. Ziziphus was, however, recognized as a distinct genus by a number 

 of authors soon after the publication of the Species Plantarum in 1753. The first of 

 these appears to have been Duhamel (Traite des Arbres, 1756, vol. 2, p. 377), with 

 one species, followed by Miller (Gard. Diet., ed. 7, 1759), with four species, Adanson 

 (Families des Plantes, 1763, vol. 2, pp. 304, 620), with six species, and by other authors. 

 The first of these authors to use the Linnaean binomial nomenclature was Philip 

 Miller in the 1768 edition of the Gardener's Dictionary, and the four species of the 

 1759 edition are there included as Ziziphus jujuba, Z. sylvestris, Z. oenoplia [oeno- 

 polia], and Z. africana. Miller, however, did not apply the name Ziziphus jujuba to 

 Rhamnus jujuba of Linnaeus, for which species it has been almost universally used 

 by subsequent authors, but to "The common Jujube," Rhamnus zizy phus of Linnaeus 

 (Z. sativa Gaertn. 1788, Z. vulgaris Lam. 1789). To conform to the present practice 

 in specific nomenclature Rhamnus jujuba L. must therefore be known as Ziziphus 

 mauritiana Lam., this being the next earliest available name applied to the species, 

 while Rhamnus zizyphus L. becomes Ziziphus jujuba Miller. Miller's Ziziphus syl- 

 vestrisisZ. lotus (L.) Lam. and his Z. africana is Z. spina-christi (L.) Willd.
